I've dabbled with Linux over the years, first with Ubuntu in the early 2010s, then Elementary OS when that dropped, and a few years ago I really enjoyed how customizable the gui was with Xubuntu. I was able to make it look just like WIndows 2000 which was really cool.
Which current distro has the best GUI, in your opinion? I find modern Ubuntu to feel a little basic and cheap. I guess I don't really like modern Gnome. I'm currently using Windows 10 LTSC which is probably the best possible version of Windows, but I'd jump to linux if I could find a distro with a gui that feels at least as polished and feature rich as Windows 10 LTSC.
I love the versatility of KDE and you can make it look amazing but at the end of the day I always end up with a Gnome-based distro for some reason. The simplicity is just so beautiful. Fedora has been my distro of choice for a few years and I don't see that changing any time soon...it just works! With gaming via Steam/Proton I don't see myself ever returning to Windows.
